i run the recomended 94 octane in my riv, was wondering if a octane boost of 10 octane numbers is alright for our cars.

it is.. however you should read the label well.

Most octane boosters don't necessarily write it out that they are only boosting you .1.. which would make you 94.1.

A couple I have seen clearly are labeled that they raise you 1 full point to say 95.

Based on some tests I've done, if you only get .1 increase, it's not worth doing. Even 1 point makes only a small difference. If you really want to lower KR, find some 100 oct race gas and mix it in.

It's safe, but unless you've got the mods to require it's use, it's pointless.

it will drop a little KR if you have any................ BUT to get the FULL effects you'd need to be able to tune it grimace

There is no way that it will work. Like the other guys said, something that claims to increase your octane by 7 points will raise it by .7. Canada has specific laws about what can be sold/advertised in octane boosters. If you can find it in a store, it doesn't work.

Octane boosters are also notorious for gumming stuff up, so I would stay away from them. They are gimmicks. Their secret ingredient is usually toluene, or xylene, which you can buy yourself for maybe $6/ gal instead of 10 bucks for 12 oz.

Our pcm's are learning PCM's. It takes around 100 miles to know that your car has learned better fuel etc. I agree with the comment about, yes it's safe...but won't help.

On tuning. A Tech II is the most advanced diagnostic tool available for our cars. This is because it is the GM tool for all body and engine modules/pcm. It can flash a new OS to the pcm. To my knowledge though..you can not use it to tune the car well.

PostSubject: Fuel Additives..   fuel cleaners & octane boost additives? EmptyMon Apr 07, 2008 11:14 am

Im wandering what you guys think of fuel additives..

STP Gas Treatment?

Shell Fuel System Cleaner?

Octane booster?.....already asked about this and dont think it does jack shit..of anything messes up the firing..i think only works with 87 octane with the 3800..

Fuel Injector Cleaner?

Anything you guys recommend or condemn?


and why every 3000 miles and not every gas tank for some of the things like the system cleaners...?

thanks!

I think a lot of those cleaners are BS. I think one of the best is seafoam. Theres a write-up on how to use it somewhere on here. As far as an octane booster paint thinner ( toluene) will increase your effective octane rating and is a lot a cheaper. I think you use like 1 oz per gallon of gas and it adds a point. But look up more about that... been a while since chem class.

I use Chevron Techron Concentrate (12 gal treatment) every 5k miles or so. It's pricey, and I don't know if it works, but I believe it does. Still on original injectors at 156k miles. Haven't had a problem with fuel delivery yet that I know of. I've only used Sea Foam maybe once in the fuel, a very long time ago.

The cleaners that cost $1.99 - I have less faith in them.

I agree with Aaron. I don't know why but I think the chevron stuff is a good cleaner. I put it in the 20 gal treatment every oil change. Does it work? I don't know.

The only octane boost I trust is the one I make. I add 1 gallon of Toluene and/or Xylene depending on my requirements. Lately I've been tuning to run with no octane boost but do a little research and you'll find you can make your own cheaper than any bottle of mystery octane boost and you'll know what's in it.

the fuel 'cleaners' are supposed to remove deposits from injectors or other places around the tank. It takes a while for these supposed deposits to build up in the first place, and not worth it to have a cleaner added all the time. Some gas stations claim to have all that cleaner crap in their gas all the time, and so theoretically running Shell SuperClean or whatever they call it eliminates the need for a FI cleaner down the road.

Who really knows how dirty your injectors are? The only way to find out is to remove them and have them flow tested.

I wouldn't do any more than mentioned above unless you think there's a problem. If there's a bigger problem, an in-tank additive isn't likely to get rid of it anyway.

Shell V-power includes detergents, but I don't think it's nearly as concentrated as the Techron. If you use the V-power regularly, you shouldn't need to use an additive. However, V-power is premium only... it may be worth it for us, but your average consumer is throwing their money away. The additive is less $ in the long run.

well im SORRY to hurt anyones feelings but 98% of the "injector cleaning" products in stores at this day and age are useless......... they do JACK......... the only PROVED treatment is SEA foam, it works.... but you NEED to change your fuel filter, because SOMETIMES it can get clogged....

AND for octane booster...... YOU CAN MAKE YOUR OWN..... its NOT easy........ but dont buy it..... the only guaranteed formula is made by PERMATEX. it is called NOS..... it raises the octane number up to 10 points.... its about 7 bucks but its FOR REAL.... all the others are BS

Where's the proof that 98% of fuel treatments don't work?

Where's the proof that Sea Foam works?

You need to change your fuel filter when... you use Sea Foam? Why is that?

it was either 97% or 98%.......... i learned this in a movie we watched in autoclass about E85... it also talked about the fuel additives.......... sorry I HAVE NO evidence:sad: .... but thats what i learned....... idk it saves me money by not buying it:ride: .....

Good to know. I must be using the 2-3% that works.

I do not use Sea Foam. Did the movie have anything to say about it?
